Thomas Jerome Schaefer is an American mathematician.
He obtained his Ph.D. in December 1978 from the University of California, Berkeley, where he worked in the Department of Mathematics. His Ph.D. advisor was Richard M. Karp.1234
He is well-known for his dichotomy theorem, stating that any problem generalizing Boolean satisfiability in a certain way is either in the complexity class P or is NP-complete.5
